Summary
In this chapter, we got into some hands-on cluster creation. We created a single-node cluster using Minikube and a multi-node cluster using KinD and k3d. Then, we looked at the many options to create Kubernetes clusters on cloud providers. Finally, we touched on the complexities of creating Kubernetes clusters on bare metal. The current state of affairs is very dynamic. The basic components are changing rapidly, the tooling is getting better, and there are different options for each environment. Kubeadm is now the cornerstone of most installation options, which is great for consistency and consolidation of effort.
It's still not completely trivial to stand up a Kubernetes cluster on your own, but with some effort and attention to detail, you can get it done quickly.
In the next chapter, we will explore the important topics of scalability and high availability. Once your cluster is up and running, you need to make sure it stays that way, even as the volume of requests increases. This requires ongoing attention and building the ability to recover from failures, as well as adjusting to changes in traffic.
